RAIL-ANCHOR PLATE.

Application filed March 3, 1924. Serial No 696,427.

To all whom it may concern:

Be it known that I, WARREN M. Osnonn, a citizen of the United States,residing at Chicago, in the county of Cook, State of Illinois, havinginvented certain new and useful Improvements in Rail-Anchor Plates, dohereby declare that the following is a full, clear, and exactdescription of the same.

My invention relates to improvements in tie plate structures foranchoring railway rails, and its object is to provide a novel and usefulorganization which looks the rail to the tie-plate in an improvedmanner.

The invention consists in the matters hereinafter described and thenpointed out in the claims.

In the accompanying drawing, Fig. 1 is a perspective view of the plate;Fig. 2 is a similar View of the clip, and Fig. 3 is a view incross-section on the line 3-3 of Fig. 1 with the rail and a portion ofthe underlying tie added and with a clip in place on the plate.

In the drawing the reference letter A rep resents the head of a rail, Bits base, C the web uniting the head and base, and D the tie.

The plate 1 is provided near one side with a shoulder 2 for therail-base which carries at its upper face a series of integral heavyribs 3 spaced apart along its length and rising above it and overhangingthe top edge of the rail-base when the latter is assembled on atie-plate. The plate is provided with spike-holes 4 for the spike 5outside the line of the shoulder 2 and between the ribs 3, and thecentral rib has a threaded opening to receive a set-screw 6 which bearsupon the rail-base to clamp it on the plate. The lower faces of theoverhanging ribs 8 are faced off to the contour of the rail-base whichmakes a driving fit between the ribs and the plate 1.

The opposite side of the plate 1 is provided, with elongated spike-holes7, and beyond each of these holes and spaced away from its outer end theplate is provided on its upper face with a shoulder 8 having an inwardlyinclined inner face 9. The plate is provided on its under face with arecess 10 extending from the inner end of each spikehole 7 toward itscenter and. of the same width as the spike-hole and terminating in aninner shoulder 11. The spike-holes 7 receive clips that interlock withthe rail-base B and tie plate 1 and are heeled up by the shoulders 8 towedge the opposite side of the rail-base in position under the ribs 3.The clips are made of metal having a substantially rectangular body 12constructed to overlie a spike-hole 7 and provided at its inner edgewith a depending lug 13 to abut against the rail-base and inner end ofthe spike-hole 7. The inner portion of the body 1 is provided with anupper inwardly di rected flange 14 to overlie the rail-base, and with aninwardly directed lower wing 15 to underlie the inner end of thespike-hole and seat in the recess 10 with its inner end against theshoulder 11. The wing and flange are in the same vertical plane to forma pocket or seat for the edge of the plate and rail-base, the flangebeing beveled on its under face to fit the inclination of the base, andthe lower face of the wing 15 being flush with the lower face of theplate. The lower outer part of the body is thickened transversely andbeveled or rounded as at 16 to Wedge against the shoulder 8, and itsupper end is provided with an inclined or beveled heeling-lug 17 for thehead of the spike 18. The holes 19 for the spikes 18 are outside thedepending lugs 13 and have their outerwalls in extension of the lugs 17In practice, an edge of therail-base is assembled to place under theoverhanging ends of the ribs 3, and the clips are assembled on the plateon the opposite side of the raihbase, the wings being passed downthrough the elongated spike-holes of the plate; the clips are thenmoved. inwardly toward the rail so that their flanges 14. overlie therail-base and their wings 15 underlie the inner ends of the spike-holes,and when the spikes 18 are driven to place on the ties they force theclips down on the inclined faces of the shoulders 8 to crowd the clipsinto place and seat their wings in the recesses in the under faces ofthe plates and the lugs 17 heel-up the spike-heads so that they are notforced outwardly by the lateral thrusts of the rail and the usualthroat-cutting of the spikes is obviated. The flanges and wings of theclips interlock the plates and rail-bases together so that the platesare anchored to the rail, and the clips hold the opposite side of therail-base in its drive-fit engagement with the overhanging ends of theribs 3. The clips thus interact with the ribs as they hold the railunder the ribs without putting the side stresses or lateral thrusts ofthe rail on the spikes, As the screw 6 is set down on the irail base itis advantageous to have spaced or separate overhanging ribs instead of.a single flange extending the width of the plate,; as in the formercase. the lifting action of the screw is confined to the central rib andwill have no efieot on the end ribs, whereas with a full or singleflange this lifting action affects the flange for its entire length andloosens its grip on the rail and the drive fit of the rail base betweenthe flange and plate is relaxed.

I claim:

1. A device of the class described.comprising a plate having anelongated spike-hole in one of its sides and a recess in its under facein line with the inner end of said spikehole, an inclined shoulderadjacent the outer end of said spike-hole an abutment on the oppositeside of said plate provided with a plurality of; spaced overhangingribs, a clip constructed to engage said shoulder and having a spike-holeand an overhanging flange for one side of a rail-base and an innerdepending, lug in the inner portion of said plate spil e-liole,aninwardly extending Wing at the lower end ofthe lug constructed to seatin said recess, and a heeling-lug in alinement with the outer end of theclip spike-hole. I p

2. A device ofthe class described comprising a plate having an elongatedspike-hole in one of its sides and a. recess in its under face in linewith the inner end of said spikehole, an inclined shoulder adjacent theouter end of said spike-hole, an abutment onthe o posite side of saidplate provided with a plurality of spaced overhanging ribs, the centerrib having'a threaded opening, a setscrew engaging said opening, a clipconstructed' to wedge on said shoulder and having a spike-hole andanoverhanging flange for one side of a rail-base, a depending lug in theinner end of the hole in the plate, an inwardly extending wing at thelower end oi the lug underlying the plate and a spikeheeling lug inalineinent with the outer l of said clip spike-hole. g

3. A. device of the class described eoinprising a plate having elongatedspikeholes in one oi its sides, inclined shoulders adjacent the-cuterends of said spike-holes, an abut-- ment on the opposite side oi saidplate pro vided with a plurality of spaced overhanging ribs ccnstructedto make a dri ing fit with the side of a raihbase and arranged instaggered relation transversely oi"? the plate with respect to saidspike-holes, and clips constructed to wedge on said shoulders and eachhaving a spike-hol an overhanging flange bearing onthe other side of therailbase, a depending lug in the inner end oi the hole in the plate, andan inwardly extending.

wing at the lower end of the-lug interlocking with the plate. 7

i. A device of the class described comprising a plate having anelongated spike-hole in one of its sides an inclined shoulder adjacentthe. outer end of said spike-hole, an abutment on the opposite side ofsaid plate provided with a projection overhanging one side of arail-base and having a threaded openingaa set-screw7 engaging saidopening.

a cli" constructed to en 'a 'e said shoulder p z: n

and having a spike-hole and an overhanging flang bearing on the otherside ofthe railbase and an inner depending lug in the inner portion ofsaid plate spikehole, and

an inwardly extending wing at the lower.

end of the lug interlocking, with the plate. In testimony whereof I;heretoaffix' my signature.
